Very interesting question Rob. I model for some of the reasons you mention. I became a part time naturist a few years ago and being a Life Model is, for me, being nude in a positive environment, where nudity in the Uk, in public, is not normally that acceptable. The money is not the motivation, at £15 to £20 per hour it is not significant - for a 2 hour session likely to be at least 3 hours of time and with travelling costs on top. I do find it empowering and agree to an extent about being exhibisionist but not at at sexually arousing. Just love being nude ! Picking up on Jeff's point about finding models, as a model I contact a lot of Life Drawing groups and they never reply to me, so frustrating from the model side too !
